4 Claims.

This invention relates to window guides, and more particularly a channel guide such as is used for example as a support and guide for the windows of automobiles and other vehicles.

Il An object of the invention is to provide an improved construction for such articles whereby it is of light weight, may be manufactured at low cost, will properly guide and maintain the window indefinitely without becoming distorted 10 or bent out of shape. and will resiliently grip the opposite sides of the glass to prevent it rattling or becoming loose in use.

It is also an object to provide a construction which may be easily assembled and can be 15 readily bent to follow curved edges of the windows and to conform to the outlines of the window frames.

With the foregoing and other objects in view I have devised a construction illustrated In the S0 accompanying drawing forming a part of this speciiication. It is. however, to be understood that various changes and modifications may be employed within the scope of the invention.

In this drawing:

Fig. 1 is a plan view of my improvedguide in a flat condition with parts broken away to more clearly show the construction;

Fig. 2 is a transverse section thereof substantially on line 2-2 of Fig. 1;

Fig. 3 is a transverse section on an enlarged scale taken substantially on line 3--3 of Fig. 1;

Fig. 4 is a transverse section showing the guide bent to channel shape and applied in a window frame for supporting and guiding the window;

u Fig. 5 is a similar view showing a somewhat modified construction; and

Fig. 6 is a similar view showing a still further modification.

Referring iirst to Figs. 1, 2 and 3, the guide 0 construction is built up in the flattened condition. It may be used as a window guide either inthis at condition or bent up to channel shape as shown in Figs. 4, 5 and 6. It `comprises a pair a of side or strengthening members III and II each of which is a woven member composed of fiber warp thread I2, such for example as cotton or other suitable fiber threads or yarns, and weft members I3 of resilient or spring wire inter- 5 woven with the warp threads I2.

These weft wires are preferably looped back and forth and are continuous as shown forming loops I l at their inner longitudinal edges which preferably extend somewhat beyond the inner u edges I5 of the fiber warps, although not necessarily so. They also form loops I6 at their outer or free edges. They are preferably wovenwith two wires in a single pick of the warp threads,

. although this is not necessarily so, but it is preferred as it permits the use of a greater number I of weft wires and gives greater stiffness which holds the shape better in the finished channel.

Along the outer edges of each of the stiffening members I 0 and II is a stiffening wire I l. This wire is secured along the edge of the stiffening l. member by sewing it thereto by means of threads I8 which are looped about the wire and the loops I6 ofthe stiffening member. This wire could be secured to the stiffening member by other means but it is preferably secured by this sewing as it u is less costly and` is less dificult to perform than would be the looping of the wires I3 about the stiiiening wires.

In assembling the guide a pair of these stiffening members I0 and II are secured together at 20 their inner longitudinal edges, which is preferably done by overlapping these inner longitudinal edge portions as shown in Figs. 1 and 2 and then securing or bonding them together. This may be done in various ways such for example as 25 stapling, cementing or stitching as indicated at I8. It will be seen that this overlapping of the two stiii'ening members is at the center of the guide when it is in the fiat condition, and it thus forms the bottom of the guide when it is bent to 80 the channel shape as shown in Figs. 4, 5 and 6. This connected overlapped arrangement forms a stiffer and more rigid base for the center of the guide or the base for the channel.

After the two stiifening members are assemso bled and secured or bonded together at their inner edge portions they are covered with a. cover ing or coating of latex or rubber composition or other plastic material I9. This may be applied by dipping into this plastic composition or other- 40 wise applying it to the connected stiiening members. 'I'his plastic of more or less iiuid mixture is preferably latex with vulcanizing ingredients. This might be self vulcanizing in that it vulcanizes itself after a time without heating, or it 5 might have an accelerator, or it might be vulcanized by heating. This plastic dip or mixture forms a flexible cover to cover and enclose the fibers of the stiffening members and bond them together to thus protect them from rust and the elements, and to make them weatherproof or weather resistant.

When the guide is bent to the channel shape the spring or resilient wires, preferably steel, tend u topress the sides in against and engage the 'sidesurfaces-of theglass 20 more firmly, and they Vle `in VFigyi, so-thatvwhen the glass is inserted the sides are pressed voutwardly placing the spring wires under tension so that the sides are firmly and yieldingly held against the sides of the glass, giving a rm grip which properly guides theglass and holds it againstany danger of rattling or becoming loose.

After the woven stilening members I and Il are covered with the plastic, latex or rubber material I9 by dipping or otherwise, and this cover-v ing has been dried, it is preferably covered `with a woven fabric outer covering 2|. This may cover the entire strip or it may cover theV front or inner side and extend around over the opposite reenforced edge portions and be secured to the back of the strip as shown at 22 in Fig. 3. If preferred one or more of the warp threads may be omitted at the points 23 about where the bend will occur to form a sortof hinge between the basey and the sides to permit easier bending to shape and prevent deforming of the material at the bend, or if preferred separate strips may be used, these strips being either of the same or different materials.k 'I'his woven fabric* cover may be secured to the flexible rubber covering I9 by rubber cement or other suitableadhesive, or it could be sewed to the strip. This fab-ric may be woven with the weft threads 24 of a relatively wide distance apart so that the fiber warps between them Will bulge outwardly to form ribs or cushions 25 to provide cushion guides at thev sides of the glass, or pile threads may be woven to form this cushion. a l

In the modified form of Fig. this woven cloth covering comprises relatively narrow strips 26 wrapped around the free stiffened edge portion only, and extending inwardly therefrom a short distance as indicated at 21. In this case it is preferred to provide at the bottom of the channel a longitudinal strip of felt or cloth 28 to give a cushion guide for the edge of theV glass. This may be cemented or otherwise secured to the bottom of theehannel. It will be seen that the stilfening wires l1 and the covering therefor provide .longitudinally extending inwardlyY projecting side guides or pads 29 for the sides of the glass. The stiiening sides of the channel between this edge guide and the base of the channel may be bent inwardly as indicated at 30 Fig. 6 forming an additional longitudinal guide for the glass between the edge guides 29 and the base` of the channel.`

, In Figs. 4, 5 and 6 the window frame in which the channel is mounted is shown conventionally at 3|. Asv suggested above this guide may be used in the flat condition as shown in ig's. 1, 2 and 3 as the side guides for the glass, as well as in the channel shape as in Figs. 4, 5 and 6.

This makes a guide construction which gives ka yielding resilient pressure against the sides of Having thusset forth the nature of my invention, what I claim is:

1. A channel shaped window guide comprising a pair of longitudinally extending stiffening members each comprising fibre warps and resilient wire wefts forming loops at the inner edges of the stilTcning members, said inner edge portions of said members being overlapped and secured together against lateral separation, and said members being covered with a flexible rubber composition.

2. A channel shaped window guide comprising a pair of longitudinally extending stiiening members each comprising. fibre warps Vand resilient wire wefts formingv loops at the inner edges'of the stiffening members, stiffener wires extending longitudinally along the outer edges of said members and secured thereto, the inner edge portions of said members being overlapped and secured together against lateral separation, and a flexible covering of a rubber composition enclosing said members and bonded thereto.
